If you have limited money available don´t pay for balls,. With good clubs even the free balls work reasonably well. At least if you are used to them. And even the best available balls provide only a marginal improvement with beginner clubs.
Until I became tour master I almost always used the free balls. If you want a slower meter the gi2-s and gi2-d balls are a good choice.
Don´t buy any new clubs until you reach level 35 to 50. You will reach that level quickly if you take advantage of the 880 points daily bonus if you complete at least one game a day for more than 5 days. A one random hole practice game or a a ctth tournament is enough and takes almost no time.
Your next Driver could be the WGT Pro if it has to be cheap or one of the nicer more expensive ones. Or wait for the level 49 to buy the R1 driver. This is the first driver available you will not want to replace a short time after you bought it.
Hybrids are not needed. Almost all shots you would play with a hybrid can be done reasonably well with either your Iron 3 or your wood 3. Almost all better WGT players use a 3rd wedge and no hybrid.
For irons and wedges you need a spin rating of 3 or more to get good performing equipment. Using them gets you a totally different experience than the beginner equipment. Iron shots clear obstacles and stop short after landing. Full power wedge shots will stay where they land or even roll backwards from there if you use much backspin. The Taylormade Ping and Max wedges available from level 38 to 51 are all good choices.
